the director of the earth systems science center at pennsylvania state university who wrote on his facebook page -- your response to michael mann and your koch-funded research and what this means for them? >> the koch foundation provided about 1/6 of our funding and made it clear to us the reason they funded as was we did recognize these issues were real, issues that michael mann did not think were real. i think he is wrong. there were valid questions and we expressed them. that express nothing but to light that we have reached a conclusion. i think this cartoon-like characterization of the koch foundation as been right wing, deniers, i have found that to be simply wrong. michael mann has published a lot of things that i disagree with. he has claimed there is no medieval warm period, that it is the warmest it has been 1000 years. i was part of the study that basically demonstrated his conclusions were wrong. he and i don't agree on lots of things, but i think the key thing is a small room of knowledge on which there can be universal agreement. i am hoping we will have that universal agreeme
